The authors reported a rare case of young women with neurofibromatosis type I (NF-I) who were successfully treated from the traumatic dislocation of a thoracic vertebra caused by a simple fall, and the relevant literature was reviewed. Due to various spinal dystrophic changes, the conventional posterior spinal fusion surgery was modified for the treatment. Spinal deformity is a common feature of NF-1, and a dystrophic lesion, like dural ectasia, provokes weakness in spinal structural. Unexpectedly, only seven similar cases were found...

Impaired functional movement may occur after spinal surgery, which increases risk of fall episode and hip fracture. Patients with long-segment thoracolumbar spine fusions had a significantly higher risk of hip fracture than those with only discectomies. Fall prevention is necessary due to the highly increased hip fracture risk. INTRODUCTION: Spinal surgeries are performed to treat spondylolisthesis, fractures, scoliosis, or other deformities. Impaired balance mechanisms and functional movement may occur after spinal surgery...

Currently, intervertebral disc prostheses that are designed to restore mobility to a vertebral segment are possible for the lumbar spine. The ball-and-socket joint is a constrained design, wherein the rotational axis of the intervertebral joint is forced to pass through the center of the spherical surfaces that form the joint. One advantage of ball-and-socket joints versus unconstrained designs includes better shear stability, which results in sufficient flexibility. In this study, finite element analyses were performed in preimplanted and implanted (intervertebral disc replacement [IDR]) lumbar spine (L1-S) models to examine range of motion (ROM) and the resulting mechanical responses in the implant and the adjacent bones...

BACKGROUND: Surgical site infection (SSI) following spine surgery is associated with increased morbidity, reoperation rates, hospital readmissions and cost. The incidence of SSI following posterior cervical spine surgery is higher than anterior cervical spine surgery, with rates from 4.5-18%. It is well documented that higher body mass index (BMI) is associated with increased risk of SSI after spine surgery. There are only a few studies that examine the correlation of BMI and SSI after posterior cervical instrumented fusion (PCIF) using national databases, however, none that compare trauma and non-traumatic patients...

BACKGROUND: Nonsurgically treated patients with AIS demonstrate altered scapular kinematics and decreased patient-reported shoulder function compared with typically developing adolescents. It is unknown whether surgical correction of the spine deformity has beneficial or detrimental effects on scapulothoracic joint function, as previous assessments of shoulder function following surgery have only focused on humerothoracic motion. The objective of this study was to perform a comprehensive analysis of scapular kinematics before and after PSF and compare postoperative scapular kinematics in AIS to those of a typically developing cohort...

BACKGROUND: Persistent postoperative pain is a significant problem for many children, particularly for those undergoing major surgery such as posterior spine fusion. More than two-thirds report persistent pain after spine fusion, yet factors that may contribute to poorer outcomes remain poorly understood. AIMS: This prospective, longitudinal study examined how psychologic and somatic symptoms cluster together in children aged 10-17 years with idiopathic scoliosis, and tested the hypothesis that a higher psychological and somatic symptom cluster would predict worse pain outcomes 1 year after fusion...

BACKGROUND: In modern clinical research, the accepted minimum follow-up for patient-reported outcome measures (PROMs) after lumbar spine surgery is 24 months, particularly after fusion. Recently, this minimum requirement has been called into question. PURPOSE: We aim to quantify the concordance of 1- and 2-year PROMs to evaluate the importance of long-term follow-up after elective lumbar spine surgery. STUDY DESIGN: Retrospective analysis of data from a prospective registry...
